Orbb

Designed by the Vadrigar to monitor combat in the arena, Orbb evolved beyond his [sic] specifications and became a deadly combatant.

The eerily bipedal eyeball, Orbb first entered the battleground between worlds as an uninvolved observer, constructed by the Arena Masters to watch and record the battles. Soon, it surprised its masters (and other combatants) by taking up a weapon and joining the fray. What goes on in the mind behind that glassy lens remains a mystery. The trail of carnage it leaves behind is not.
